Last year, before the gigantic hadron supercollider at CERN research facility was installed underground, a photographer captured this picture of a 1,950 metric ton tunnel containing giant magnets that will be placed in a tunnel and kept at near-zero temperatures. These mega-magnets are the biggest in the world, and will force subatomic particles to smash into each other. Want to see another one of the mega-magnets?

Holy crap. Seriously, I am in awe. This is the world's largest superconducting solenoid magnet. I want one for the outside of my apartment building. Photos by Martial Terzzini/AP.
